M. CARO BALL FOR PLAYING GAMES Filed Jan. l0, 1934 2 Sheets-Shea?l 21111114111114Inv/111111111 Patented Aug. 27, 1935 PATENT OFFICE BALL FORPLAYING GAMES Martin Caro, Brussels, Belgium Application January 10,1934, Serial No. 706,102 In Belgium January 12, 1933 This inventionrelates to balls for playing games such as football or the like andcomprises a casing having an opening for the insertion of a valvedbladder and an infiation opening diametrically positioned relative tothe first opening.

The invention also provides that the said bladder be removably connectedto the casing by means of its neck.

According to the invention, the connection between the bladder andcasing is obtained by means of an arrow-shaped member formed of iiexiblematerial. This arrow-shaped member is united with the portion of thecasing provided with the ination opening and the sharp ends of thisarrow-shaped member are adapted to be inserted through holes of a memberunited with the neck of the bladder.

According to another form of the invention, the connection between thebladder and casing is effected by means of a plate, for example made ofsteel, united to the neck of the bladder and inserted in a recessprovided in the portion of the casing having the inflation opening.

The annexed drawings show, by way of example and in a non-limitingmanner, several embodiments of the invention:

Figure 1 is a fragmentary section through the ball, according to theinvention.

Fig. 2 is a fragmentary plan view showing the details of the connectionbetween the bladder and the casing.

Fig. 3 is a fragmentary perspective view of the bladder and theconnecting device.

Fig. 4 is a section through the ball.

Fig. 5 is a plan View of the closing flap of the ball.

Fig. 6 is a fragmentary sectional view of a modified form of theinvention.

Figs. 7 and 8 are fragmentary plan and sectional views of anothermodication of the ball, according to the invention.

According to Figs. 1 and 2, the valved bladder 2 is inserted, neckforward, into the casing 3 through a hole 4, the dimensions of which arelarge enough to avoid deformation and easily allow the insertion andwithdrawal of the bladder. The neck of the said bladder is provided atits upper part with a piece 5, made of indiarubber, upon which ametallic plate 6, for example of steel, is attached by means of rivets.

When the bladder is pushed into the casing, the said plate 6 is insertedinto a recess I positioned diametrically opposite the hole 4 in theportion 8 of the casing. This recess 'I is obtained by the cooperationof the portion 8 of the CaS- ing and a piece of leather 9 sewed thereto.The said piece of leather is provided with a hole I having a shapesimilar to that of the metallic plate and is positioned in front ofanother hole II provided in the portion 8 of the casing for theinflation of the bladder. The plate 8 is inserted through hole Ill intothe recess and is then turned perpendicularly to the first position, inorder to take the position illustrated in Fig. 2. Since plate B is madeof elastic steel, it takes the shape of the casing.

According to Fig. 6, a rigid, short and threaded pipe I6, made ofBakelite for instance, is united to the portion 8 of the casing andpositioned axially of the hole II. In order to obtain the connectionbetween the bladder 2 and the casing, the said pipe is screwed into holeIl of the neck of the bladder. This latter hole is internally threadedand may be metallically lined. The screwing of the pipe I6 into the holeof the neck may be effected from the exterior of the ball.

When the ball is iniiated a stopper I 8, the head of which is hiddenunder a piece of leather, is screwed into the pipe I6 until its leathercomes into the plane of the leather of the casing. The screwing of saidstopper is obtained by means of a tool which enters into holes such asI9 provided into the head of the said stopper. In proportion as the saidbladder inates, the casing is automatically closed without tools bymeans of the flap I 3 being of leather (Figs. 4 and 5) and which issewed in the proximity of the hole 4. This fiap is provided upon itsinterior side with a plate I4, made of mica, covered with a piece ofleather sewed to the said flap. The dimensions of this plate I4 aregreater than those of the hole 4 and prevent the deformation of the ballunder the pressure of the inflated bladder.

The stitching providing the connection between the piece 9 and thecasing and equally the stitching in the closing flap I3 are similar tothe stitching of an ordinary ball. Besides, due tothe fact that therecess 'I and the hole 4 are diametrically positioned, the ball isperfectly balanced.

According to Figs. 7 and 8, a kind of arrow-like member I8, made offlexible material and provided with a hole I9, is sewed to the portion 8of the casing, so that its hole is axially aligned with the hole I I ofthe said casing. The neck of the bladder is provided at its upper partwith a piece 2 I, made of exible material such as leather, provided withtwo holes 22 through which the sharp ends 23 of the arrow-like member I8are inserted (see Fig. 8). VBy this means, the bladder is connectedtothe portion 8 of the casing and is maintained in this position bymeans of barbs 24 of the arrow i3, which engage against the lower sideof the piece 2E. When this connection is obtained, the bladder isiniiated.

What I claim is:-

1. A ball comprising a bladder, a casing provided with openings for theintroduction of the bladder and for ination of the bladder, a piece offlexible non-metallic material axed to the interior of the casingadjacent the inflation opening and provided with two tongues, and acollar of iieXible non-metallic material afxed to the bladder andprovided with apertures for the reception of said tongues for connectingthe bladder to the casing.

2. A ball comprising a bladder, a casing provided with openings for theintroduction of the bladder and for inflation of the bladder, a collarof flexible non-metallic material attached to the bladder and providedwith apertures, a piece of exible non-metallic material attached to theinterior of the casing adjacent the inflation opening and provided witharrowhead like tongues adapted to enter the apertures in the collarattached to the bladder, and barbs on said tongues adapted after beingpassed through the apertures in the collar to engage one face of thecollar to avoid accidental removal of the tongues from said apertures.

3. A ball comprising a bladder, an outer casing provided with twodiametrcally opposed openings, one of said openings serving for theintroduction of the bladder and the other opening serving for inflationof the bladder, a flap positioned on the' interior of the casing andattached thereto adjacent the opening for the introduction of thebladder in the casing, a plate of ilexible semi-rigid material ofdimension greater than that of the opening for the introduction of thebladder, and means for securing said plate to the internal face of theap for closing the bladder 20 introducing opening.
